Abstract
Therapeutic practice is based on theories displaying different profiles, which imply philosophical traits. My main concern is to discover these traits, in my eyes a neglected issue. The question of what sort of psychology helps for enhancement also depends on the inherent philosophical approach, including an idea about human nature. I try to identify philosophical features in two main psychological concepts: in the empirically founded psychoanalytic one dealing with psychic mechanisms, which could be observed in patients; and the so-called analytical one based on a philosophy of nature, I call an ontological perspective. For characterising these two features, it seems appropriate to me to go back to the founder figures Sigmund Freud and C. G. Jung. It is open for discussion and interests which theory both representatives and their followers developed will be used for practice or research.
